Connection of a TW156H
Î Actuate the hand lever (Pos. 2) ( Figure 1 ). The clamping
jaws open.
Î
Be careful to place the connector with actuated clamping
lever (Pos. 2) straight and fully up to the stop onto the test
piece. Doing so will prevent any damage to the seal on the
test piece and damage to the connector and ensure a
correct connection.
Attention: Insert the connector carefully and not with
force onto the test piece.
Î
Release the hand lever (Pos. 2). The connector tightens itself
to the test piece and creates a pressure-tight connection.
( Figure 2 ).
Attention: Make sure that the clamping jaws on the test
piece grip correctly, that the connector is seated properly
(it must not wobble) and that the pressure-tight connection
has been made.
Î
In addition, screw the test piece into the connector hand-tight with a
1
/

turn
( Figure 3 ).
Attention: The red ring must no longer be visible ( Figure 4 ). Only then is the connec-
tor connected correctly. Otherwise the connector may spring out of place and
medium may escape. If the red ring is still visible, then the connector is not
correctly connected ( Figure 5 ). Repeat the connecting procedure.
Î Pull lightly on the connector in the direction opposite that of the connection to
make sure that the connector is firmly in place.
- The connector is now connected pressure-tight to the test piece.
Î To start the testing procedure, apply pressure to media inlet ‘B1’.
